Android开发实现自定义Toast、LayoutInflater使用其他布局示例

public class MainActivity extends Activity {
  Toast toast;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //应用布局文件
    View insideView = LayoutInflater.from(MainActivity.this).inflate(R.layout.cell, null);
    LinearLayout linearLayout = (LinearLayout) insideView.findViewById(R.id.cell);
    ImageView imageView = (ImageView) insideView.findViewById(R.id.image1_Toast);
    TextView textView = (TextView) insideView.findViewById(R.id.textToast);
    imageView.setImageResource(R.drawable.warming);
    textView.setText("你的app 炸了！！");
    //建立提示消息对象
    toast = new Toast(this);
    toast.setView(insideView);
  }
  //按钮点击时弹出
  public void prev(View source){
    toast.show();
  }
}
