我是Android开发的初学者。我正在制作水平方向的时钟。应用程序在没有TextView的情况下运行良好。我已经在清单文件中将屏幕方向更改为水平。但是每当我在活动中设置Textview时，它都会崩溃应用程序。编译器会构建apk而不会出现任何错误。
这是清单文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.soumyadeep.maclauncher">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity"
android:screenOrientation="landscape"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Main2Activity"
android:screenOrientation="landscape"
>
</activity>
</application>
这是我的Java活动代码。
package com.example.soumyadeep.maclauncher;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.animation.Animation;
import android.view.animation.DecelerateInterpolator;
import android.view.animation.RotateAnimation;
import android.widget.ImageView;
import android.widget.TextView;
public class Main2Activity extends AppCompatActivity {
TextView mi,hr,sec;
static int hrs,secs,min;
RotateAnimation rotate;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
mi=(TextView)findViewById(R.id.min);
sec=(TextView)findViewById(R.id.sec);
hr=(TextView)findViewById(R.id.hr);
rotate=new RotateAnimation(0.0f,359.0f,RotateAnimation.RELATIVE_TO_SELF,0.5f,RotateAnimation.RELATIVE_TO_SELF,0.5f);
rotate.setFillAfter(true);
rotate.setDuration(1000);
rotate.setRepeatCount(Animation.INFINITE);
rotate.setInterpolator(new DecelerateInterpolator());
rotate.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
secs=secs+1;
if(secs>=60)
{
int a=secs/60;
secs=0;
min=min+a;
mi.setText(mi+"");
}
if(min<10){
mi.setText("0"+mi);
}
if (secs<10){
sec.setText("0"+secs);
}
if(min>=60)
{
int a=min/60;
min=0;
hrs=hrs+a;
hr.setText(hrs+"");
mi.setText(min+"");
}
if(hrs==24)
{
hrs=0;
hr.setText(00+"");
}
if(secs>=10){
sec.setText(secs + "");
}
}
});
ImageView img=(ImageView)findViewById(R.id.blc);
img.startAnimation(rotate);
}
}
android监视器错误
