Question

我尝试使用代码在主布局中添加两个布局但是在将布局设置为框架并将其添加到视图中时会出现错误

public class MainActivity extends Activity {

FrameLayout rootLayout;
FrameLayout frame1,frame2;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    rootLayout=new FrameLayout(getApplicationContext());
    frame1=(FrameLayout)findViewById(R.layout.frame1);
    frame2=(FrameLayout)findViewById(R.layout.frame2);

    LayoutParams param1=new FrameLayout.LayoutParams(180,300);
    LayoutParams param2=new FrameLayout.LayoutParams(180,300);

    param1.gravity=Gravity.LEFT;
    param2.gravity=Gravity.RIGHT;

    param1.setMargins(0, 0, 30, 30);
    param2.setMargins(30, 0, 0, 30);


    frame1.setLayoutParams(param1);
    frame2.setLayoutParams(param2);

    rootLayout.addView(frame1);
    rootLayout.addView(frame2);

}
}

您必须从其父frame1中删除frame2和View个观看次数...

这可能对你有帮助......

    FrameLayout rootLayout;
    FrameLayout frame1, frame2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        rootLayout = new FrameLayout(this);
        frame1 = (FrameLayout) getLayoutInflater().inflate(R.layout.frame1,null);
        frame2 = (FrameLayout) getLayoutInflater().inflate(R.layout.frame2, null);

        FrameLayout.LayoutParams param1 = new FrameLayout.LayoutParams(180, 300);
        FrameLayout.LayoutParams param2 = new FrameLayout.LayoutParams(180, 300);

        param1.gravity = Gravity.LEFT;
        param2.gravity = Gravity.RIGHT;

        param1.setMargins(0, 0, 30, 30);
        param2.setMargins(30, 0, 0, 30);

        frame1.setLayoutParams(param1);
        frame2.setLayoutParams(param2);

        rootLayout.addView(frame1);
        rootLayout.addView(frame2);
        setContentView(rootLayout);
    }
