Android自定义顶部标题栏

本文实例为大家分享了Android自定义顶部标题栏展示的具体代码，供大家参考，具体内容如下

思路及实现步骤

1.定义标题栏布局
2.自定义TitleActivity控制标题栏按钮监听
3.在TitleActivity中实现标题栏以下内容切换

首先定义标题栏

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  android:id="@+id/layout_titlebar" 
  android:layout_width="match_parent" 
  android:layout_height="52dp" 
  android:background="#ed4255" > 
 
  <TextView 
    android:id="@+id/text_title" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:ellipsize="marquee" 
    android:gravity="center_horizontal|center" 
    android:singleLine="true" 
    android:text="标题栏" 
    android:textColor="#ffffffff" 
    android:textSize="20dp" /> 
 
  <Button 
    android:id="@+id/button_backward" 
    android:layout_width="60dp" 
    android:layout_height="match_parent" 
    android:background="@drawable/title_button_selector" 
    android:drawableLeft="@drawable/back_arrow" 
    android:drawablePadding="6dp" 
    android:ellipsize="end" 
    android:gravity="center" 
    android:onClick="onClick" 
    android:paddingLeft="5dp" 
    android:singleLine="true" 
    android:text="返回" 
    android:textColor="#ffffffff" 
    android:textSize="18dp" 
    android:visibility="invisible" /> 
 
  <Button 
    android:id="@+id/button_forward" 
    android:layout_width="60dp" 
    android:layout_height="match_parent" 
    android:layout_alignParentRight="true" 
    android:background="@drawable/title_button_selector" 
    android:drawablePadding="6dp" 
    android:ellipsize="end" 
    android:gravity="center" 
    android:onClick="onClick" 
    android:paddingLeft="5dp" 
    android:singleLine="true" 
    android:text="提交" 
    android:textColor="#ffffffff" 
    android:textSize="18dp" 
    android:visibility="invisible" /> 
 
</RelativeLayout> 

定义控制标题栏按钮和标题栏以下内容的布局

 <?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  android:orientation="vertical" > 
 
  <!-- Title --> 
 
  <include layout="@layout/layout_titlebar" /> 
 
  <FrameLayout 
    android:id="@+id/layout_content" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="#fff" > 
  </FrameLayout> 
 
</LinearLayout> 

注：此处使用 <include> 标签引入标题栏，且下方有定义一个空的FrameLayout的布局。

定义TitleActivity控制按钮及布局

package org.gaochun.widget; 
 
import org.gaochun.ui.R; 
 
import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.ViewGroup.LayoutParams; 
import android.widget.Button; 
import android.widget.FrameLayout; 
import android.widget.TextView; 
import android.widget.Toast; 
 
 
/** 
 * @author gao_chun 
 * 自定义标题栏 
 */ 
public class TitleActivity extends Activity implements OnClickListener{ 
 
  //private RelativeLayout mLayoutTitleBar; 
  private TextView mTitleTextView; 
  private Button mBackwardbButton; 
  private Button mForwardButton; 
  private FrameLayout mContentLayout; 
 
 
  @Override 
  protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setupViews();  //加载 activity_title 布局 ，并获取标题及两侧按钮 
  } 
 
 
  private void setupViews() { 
    super.setContentView(R.layout.activity_title); 
    mTitleTextView = (TextView) findViewById(R.id.text_title); 
    mContentLayout = (FrameLayout) findViewById(R.id.layout_content); 
    mBackwardbButton = (Button) findViewById(R.id.button_backward); 
    mForwardButton = (Button) findViewById(R.id.button_forward); 
  } 
 
  /** 
   * 是否显示返回按钮 
   * @param backwardResid 文字 
   * @param show true则显示 
   */ 
  protected void showBackwardView(int backwardResid, boolean show) { 
    if (mBackwardbButton != null) { 
      if (show) { 
        mBackwardbButton.setText(backwardResid); 
        mBackwardbButton.setVisibility(View.VISIBLE); 
      } else { 
        mBackwardbButton.setVisibility(View.INVISIBLE); 
      } 
    } // else ignored 
  } 
 
  /** 
   * 提供是否显示提交按钮 
   * @param forwardResId 文字 
   * @param show true则显示 
   */ 
  protected void showForwardView(int forwardResId, boolean show) { 
    if (mForwardButton != null) { 
      if (show) { 
        mForwardButton.setVisibility(View.VISIBLE); 
        mForwardButton.setText(forwardResId); 
      } else { 
        mForwardButton.setVisibility(View.INVISIBLE); 
      } 
    } // else ignored 
  } 
 
  /** 
   * 返回按钮点击后触发 
   * @param backwardView 
   */ 
  protected void onBackward(View backwardView) { 
    Toast.makeText(this, "点击返回，可在此处调用finish()", Toast.LENGTH_LONG).show(); 
    //finish(); 
  } 
 
  /** 
   * 提交按钮点击后触发 
   * @param forwardView 
   */ 
  protected void onForward(View forwardView) { 
    Toast.makeText(this, "点击提交", Toast.LENGTH_LONG).show(); 
  } 
 
 
  //设置标题内容 
  @Override 
  public void setTitle(int titleId) { 
    mTitleTextView.setText(titleId); 
  } 
 
  //设置标题内容 
  @Override 
  public void setTitle(CharSequence title) { 
    mTitleTextView.setText(title); 
  } 
 
  //设置标题文字颜色 
  @Override 
  public void setTitleColor(int textColor) { 
    mTitleTextView.setTextColor(textColor); 
  } 
 
 
  //取出FrameLayout并调用父类removeAllViews()方法 
  @Override 
  public void setContentView(int layoutResID) { 
    mContentLayout.removeAllViews(); 
    View.inflate(this, layoutResID, mContentLayout); 
    onContentChanged(); 
  } 
 
  @Override 
  public void setContentView(View view) { 
    mContentLayout.removeAllViews(); 
    mContentLayout.addView(view); 
    onContentChanged(); 
  } 
 
  /* (non-Javadoc) 
   * @see android.app.Activity#setContentView(android.view.View, android.view.ViewGroup.LayoutParams) 
   */ 
  @Override 
  public void setContentView(View view, LayoutParams params) { 
    mContentLayout.removeAllViews(); 
    mContentLayout.addView(view, params); 
    onContentChanged(); 
  } 
 
 
  /* (non-Javadoc) 
   * @see android.view.View.OnClickListener#onClick(android.view.View) 
   * 按钮点击调用的方法 
   */ 
  @Override 
  public void onClick(View v) { 
 
    switch (v.getId()) { 
      case R.id.button_backward: 
        onBackward(v); 
        break; 
 
      case R.id.button_forward: 
        onForward(v); 
        break; 
 
      default: 
        break; 
    } 
  } 
} 

MainActivity中调用时直接 extends TitleActivity 使用之前在TitleActivity中定义的方法
