Question

我有一个以下代码翻转页面，但显示相同的布局和相同的活动我想更改此代码当按钮按下它显示另一个屏幕有不同的布局如何可能？源代码如下：

 package com.samir;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.AccelerateInterpolator;
import android.widget.Button;
import android.widget.RelativeLayout;

import com.samir.anim.DisplayNextView;
import com.samir.anim.Rotate3dAnimation;

 public class MainActivity extends Activity implements OnClickListener {

Button btnRotateit, btnRotateBack;
RelativeLayout mContainer, relChild1, relChild2;
private boolean isFirstView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mContainer = (RelativeLayout) findViewById(R.id.mainlayout);
    relChild1 = (RelativeLayout) findViewById(R.id.child1);
    relChild2 = (RelativeLayout) findViewById(R.id.child2);

    btnRotateit = (Button) findViewById(R.id.btnrotate);
    btnRotateit.setOnClickListener(this);
    btnRotateBack = (Button) findViewById(R.id.btnback);
    btnRotateBack.setOnClickListener(this);
}

@Override
public void onClick(View view) {
    switch (view.getId()) {
    case R.id.btnrotate:
        isFirstView = true;
        applyRotation(0, 90);
        break;
    case R.id.btnback:
        isFirstView = false;
        applyRotation(0, -90);
        break;
    default:
        break;
    }

}

private void applyRotation(float start, float end) {
    final float centerX = mContainer.getWidth() / 2.0f;
    final float centerY = mContainer.getHeight() / 2.0f;

    // The animation listener is used to trigger the next animation
    final Rotate3dAnimation rotation = new Rotate3dAnimation(start, end,
            centerX, centerY, 310.0f, true);
    rotation.setDuration(1200);
    rotation.setFillAfter(true);
    rotation.setInterpolator(new AccelerateInterpolator());
    rotation.setAnimationListener(new DisplayNextView(isFirstView,
            mContainer, relChild1, relChild2));

    mContainer.startAnimation(rotation);

}
     }

    this.isFirstView = isFirstView;
}

@Override
public void onAnimationEnd(Animation animation) {
    mContainer.post(new SwapViews());
}

@Override

Answer 1

在onclicklistener方法上使用setContentView赞：

setContentView(R.layout.layout);

编辑：我想您希望在btnRotateit按下时显示relChild1和relChild2并再次按btnRotateBack然后再显示mContainer，然后尝试：

在btnRotateit onclick方法：

上添加代码

relChild1.setVisibility(View.VISIBLE);
relChild2.setVisibility(View.VISIBLE);
mContainer.setVisibility(View.GONE);

并在btnRotateBack onclick方法上添加代码：

relChild1.setVisibility(View.GONE);
relChild2.setVisibility(View.GONE);
mContainer.setVisibility(View.VISIBLE);

尝试这个并让我知道。

Answer 2

onClick(View v)
{
    setContentView(R.layout.another);
                            ^^^^^^^ 
}

编辑： 例如，您有两个视图，可以设置可见性INVISIBLE或GONE

并在onClick中应用旋转并更改组件的可见性

Answer 3

检查此代码

 private View view = null ;
 Button addbutton = null;
 ViewGroup parent = null;
 LayoutInflater inflater = null;

 inflater= (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
 addbutton = (Button)findViewById(R.id.btnAdd);

 parent = (ViewGroup) findViewById(R.id.mainxml);


 addbutton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View view) {
        view = inflater.inflate(R.layout.other, null);
        parent.addView(view);
   }
});

Answer 4

从您对vishwa的回复中，您似乎不希望更改现有活动的布局，以至于更改为其他活动。在哪追逐：

Intent intent = new Intent(this, secondpage.class);
startActivity(intent);

当按下按钮时，如何显示另一个布局？
