Question

我在屏幕上有按钮，当我按下屏幕上的按钮时，我想要进行不同的活动。

应用程序正在运行，但按钮停止。

请帮帮我。我正在学习android。抱歉英文不好。

我的班级档案;

public void git1(View view) {

    this.view = view;
    Intent intent1 = new Intent(getApplicationContext(),first.class);
    startActivity(intent1);

}

public void git2(View view) {

    this.view = view;
    Intent intent2 = new Intent(getApplicationContext(),second.class);
    startActivity(intent2);

}

public void git3(View view) {

    this.view = view;
    Intent intent = new Intent(getApplicationContext(),third.class);
    startActivity(intent);

}

public void git4(View view) {

    this.view = view;
    Intent intent = new Intent(getApplicationContext(),fourth.class);
    startActivity(intent);

}

public void git5(View view) {

    this.view = view;
    Intent intent = new Intent(getApplicationContext(),fifth.class);
    startActivity(intent);


}

That's how the design looks.

我的XML文件;

例如：

@Override
public void onCreate(Bundle savedInstanceState) {
Button b1 = (Button) findViewById(R.id.buttonplay);       
b1.setOnClickListener(this);
//{YOUR APP}
}


@Override
public void onClick(View v) {
// Perform action on click
switch(v.getId()) {
case R.id.buttonplay:
    //Play voicefile
    MediaPlayer.create(getBaseContext(), R.raw.voicefile).start();
    break;
case R.id.buttonstop:
    //Stop MediaPlayer
    MediaPlayer.create(getBaseContext(), R.raw.voicefile).stop();
    break;
 }

}}
