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

定义控制标题栏按钮和标题栏以下内容的布局

注：此处使用 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

    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);

    if (mBackwardbButton != null) { 
      if (show) {

      } else {

      } 
    } // else ignored 
  } 
 
   
  protected void onBackward(View backwardView) { 
    Toast.makeText(this, "点击返回，可在此处调用finish()", Toast.LENGTH_LONG).show(); 
    //finish(); 
  } 
 
   
  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(); 
  } 
 
   
  @Override 
  public void setContentView(View view, LayoutParams params) { 
    mContentLayout.removeAllViews(); 
    mContentLayout.addView(view, params); 
    onContentChanged(); 
  } 
 
 
   
  @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
